The world of REANIMAL is riddled with hidden secrets that only keen-eyed players can discover as they explore each area.

Here’s a quick guide to help you find the hidden code for the bunker and unlock the Secret Bunker achievement/trophy in REANIMAL.

REANIMAL Secret Room with Conch Head Mask

To get the hidden code for the Secret Bunker in REANIMAL, players will need to visit the secret area in Chapter 1: Dead in the Water. The area is just after you complete the boiler puzzle at the Mill, and exit out in the open to find a draisine. There are two different doors to the right side of the draisine, one is lit by a bulb, and the other is dark.

Once players head inside this area (marked in the image), they’ll enter another part of the mill with a catwalk leading up to a small office. Inside the office, you’ll find a Conch Head mask on the ground. If you look closely at the cardboard boxes to the right, you’ll see a pattern of white dots on them. This is the hidden code that you can use for the Secret Bunker achievement in REANIMAL.

How to Use the Secret Bunker Code in REANIMAL

Secret Bunker is located at the start of REANIMAL’s Chapter 6: Nobody Left Behind. As our characters make their way out of the car crash into the tunnels, they’ll arrive inside an old, darkened bunker. There’s also a disabled panel in the room with buttons and a switch on it, but you have to restore power to the bunker before using it.

To restore power, head outside the door to the right, and you’ll spot a generator on the platform. Interact with the generator to start it up, which should turn the lights on inside the bunker.

Now simply return to the bunker, and you’ll use a pair of binoculars to spot a code on Cannon Island with similar dots. This is the first code you’ll need to enter into the machine. So, push the buttons to align the lights according to the first code (bottom, middle, top, bottom) to call in a crate of shells that you’ll later use to progress the chapter.
